Filed: 1942-05-01
Abstract: 556,626. Motor power plant; cylinders, cooling. LARKIN, E. E. May 1, 1942, No. 5917. Addition to 544,816 [Group XXVI]. [Class 7 (ii)] [Also in Group XXVI] In a power plant in which the exhaust from an internal-combustion engine 10 is supplied along a path 22, 30 to and from a boiler 24 for vaporizing liquid fuel to be used expansively in an engine or turbine 38 for generating power and then condensed, at least part of the condensate is returned to the boiler along a second path distinct from the first, and fuel-supply means 18 is arranged to supply to the engine 10 a liquid fuel of greater specific gravity than the fuel vaporized in the boiler. As shown, the exhaust from the engine 10 passes through tubes 26 in the boiler 24 to an outlet pipe 30. Light fuel vaporized in the boiler is conveyed by a pipe 34 to the turbine 38 and thence through a water-cooled condenser 42 to a receiver 50 having a float-controlled inlet 54 for make-up fuel. A pump 58 conveys fuel from the receiver through a pipe 62 and the cylinder jacket 16 of the engine to an outlet pipe 64 surrounding the exhaust pipe 22. Branches 66, 68 leading respectively to the boiler 24 and to the condenser 42 are controlled by connected valves 70, 72 actuated from a float 76 in the boiler, so that the liquid is partly supplied to the boiler and partly bypassed to the condenser. Heavy fuel is normally supplied to the engine 10 from a supply pipe 96 by a pump 18 and injection device 20 ; a two-way rotary valve 88 enables the heavy fuel to be replaced wholly or partly by light fuel from the pipe 62 through a connection 86.

Title: Improvements in or relating to vibration damping devices
IPC: F16F15/067
Filed: 1949-03-04
Abstract: 661,481. Aperiodic spring devices. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). March 3. 1950 [March 4, 1949], No. 5923/49. Class 108(iii) A vibration damping device for supporting a machine comprises a base which supports two yieldable devices arranged to yield one after the other, and one of which comprises means (e.g. a flexible column) arranged substantially vertically above the base and arranged to yield by flexing laterally of its length, a platform for supporting the machine. and connections, including the other yieldable device, between the platform and the upper end of the laterally flexing means. The invention is described as applied to a shoe-leather cutting press of the kind described in Specification 22023/05, [Class 31]. The foot 36 of each leg of the press is clamped by a nut 38 to a plate 14 which is rigid with a tube 40 vertically slidable on a guide 42. A plate 44 rigid with the upper end of the tube 40 bears on coiled springs 46. An abutment plate 48 for the lower end of the springs 46 is supported by rods 50 suspended from a plate 54 which is connected rigidly to a crosshead 60 by a tubular member 56. The crosshead 60 is supported from a base 32 by a pair of rods 64 loaded as columns. their ends being located in sockets 62, 66. Under the static load of the press, the rods 64 are bowed as shown, deflection being guided by radial slots 75, 76 in the plates 14, 44, 54, 48, Deflection in one direction is limited by engagement with the inner ends of slots 76, and in the other by engagement with pins 82 bridging the slots 76. The stiffness of the rods 64 under load is adjupsted by rotation of a plate 68 in threaded engagement with the member 56. The plate 68 is locked by means of a pin 70 which may engage either of diametrically opposed holes 73 in the plate. A cylindrical casing 86 (only a fragment shown in the Fig.) extending upwardly from the base 32, surrounds the unit but has a cut-away portion to provide for movement of the foot 36. The casing 86 is secured by a nut 90 to a rod 88 which extends concentrically within the member 56 and tube 40 and is rigid with the guide 42. In operation, the rods 64 are operative and function as columns in series with the springs 46 under static load. Under the dynamic load due to a cutting operation, the rods 64 become inoperative since they abut against the inner ends of the slots 75, 76. This renders the device aperiodic in response to dynamic load.

Title: Method and apparatus for making corrugated web materials such as battery separators
IPC: H01M50/406
Filed: 1966-02-10
Abstract: 1,116,762. Corrugating paper; paperboard. RIEGEL PAPER CORPORATION. 10 Feb., 1966 [1 March, 1965], No. 5941/66. Headings D1S and D2B. Corrugated web material used to form battery separators having a predetermined rib height and a predetermined spacing between adjacent ribs is made by continuously supplying an uncured web material including a curable hardening component, imparting rib corrugations to the web which corrugations exceed the predetermined rib height and are spaced at intervals less than the predetermined spacing, controllably reducing the rib height while increasing the rib spacing by application of predetermined tension to the web to achieve the predetermined height and the predetermined spacing, and curing the hardening component to permanently fix the ribs at the predetermined height and spacing. A paper web 10, preferably comprising 50% by weight of fibres in equal amounts of cotton linters and unbleached softwood kraft, 42% of a thermosetting phenolic resin and 8% of volatile matter and wetting agents, is unwound under constant tension from a stand 11 and passes between opposed pairs radiant heaters at a preheating station 12 to heat the web to 300F to soften it and make it pliable. Rollers 14, 15 provided with grooves 17 and metal blades 16, respectively, Fig. 2, form transverse corrugations in the web. The roll 14 is adjustable towards and away from the roll 15 by a handwheel 18. The corrugated web 22 is transferred by belts 25 to a partial curing chamber 19 having a conveyor 20 comprising a wire screen 23 the upper run of which passes over a vacuum box 24 which causes the lower flat surface of the web 22 to engage the conveyor 20. Gas fired radiant heaters 21 substantially set the ribs and partially cure the thermosetting resin. Additional thermosetting phenolic resin is applied to the tops of the ribs of the partially cured web 29 by an applicator roller 28 supplied from a reservoir 27. The web is carried by a chain conveyor 31 through a final curing chamber 30 in the form of a hot air oven maintained at about 375F. The conveyor 31 is driven at a speed slightly greater than the web so there is a slight relative movement therebetween to prevent the chain marking the web, surface. The web then passes onto a second conveyor screen 33 and over a suction table 34, the drawing of air through the web promoting rapid cooling thereof. The cured web 35 is pulled by resilient rollers 37 over saw 36 which sever the web longitudinally. Individual battery separators 39 are formed a cutter 38 which severs the web transversely. To apply longitudinal tension to the web to achieve the predetermined rib height and spacing, the conveyor 20 and/or the pull rollers 37 are driven at a speed greater than the speed of the corrugating rolls 14, 15. Take-off boxes 42, 45, 47, 49, 50, 51 drive the rolls 14, 15, the conveyor 20, the rollers 37, the conveyor 31, the conveyor 33 and the cutter 38, respectively, and are operated by a main shaft 43 driven by a variable speed motor 44.
